Lingering showers kept roads slick through early Tuesday afternoon, making driving treacherous, in areas. The storm has since moved off to the east. But a cold air mass has settled over the region, and it produced record cool temperatures today across the county.

The chilly weather will last into the weekend, with temperatures running five degrees below normal Wednesday and Thursday in San Diego, and a 2-3 degrees off Friday and Saturday, says the National Weather Service. A low pressure system is expected to drop south on Thursday night, keeping the weather unsettled and cool. There's currently a 20 percent change that the next storm will produce significant rain locally. But forecasters say the system could stall over northern Baja, which would alter the picture.
